Battlestar Galactica

This update of the late-1970s series takes a decidedly darker tone as what's left of humankind struggles for survival against the robot Cylons, who have killed millions. The Galactica, led by William Adama, protects a patched-together fleet of civilians -- led by de facto president Laura Roslin -- in search of a mythical planet called Earth.

A spinoff of "Star Trek: The Next Generation," "Deep Space Nine" is set on a space station near the planet Bajor. This time, Commander Benjamin Sisko is in charge of a diverse crew.

Sisko and the crew must fight off rival alien species who want control of Deep Space Nine because of its strategic position close to a wormhole, which allows speedy travel to the far reaches of space.
